Eaton Power Xpert 9395C UPS Installation and Operation Manual 164000821—Rev 06 131
Every battery cabinet must have a UVR-type DC circuit breaker with an auxiliary contact. Failure to use this type
of circuit breaker may cause severe damage to the UPS and create a personnel hazard. Note that all battery
cabinets provided by the UPS manufacturer have this circuit breaker as a standard feature.
NOTE Do not close battery breaker until pre-charge is complete (i.e. Bypass Mode or Online
Mode has been achieved).
NOTE If "Batteries Disconnected" and/or "Battery Breaker Open" alarms are present, close the
battery breaker.
• The rectifier and inverter turn on. The inverter continues to ramp up to full voltage. 'DC Starting' will
appear on the header section of the screen.
• When the inverter reaches full voltage, the static switch turns off. Power is now supplied to the critical
load in Online mode. It takes approximately one minute for the UPS to achieve Online mode.
• The Online status indicator is illuminated. The UPS status indicates ONLINE on the header section of
the screen. The UPM status indicates Active on the UPS Module Map Screen (see Figure 87 ).
9. Close the battery breaker.
To activate or enable/disable any of the UPS operational modes, follow the online screen prompts.
To obtain any system information, follow the on screen prompts to get to the proper screen. The operator
cannot inadvertently cause a system dump or disconnect unless they override a warning pop-up. Value or
information screens DO NOT affect system operation.
If a UPS’s output is on, do not close the MOBs of any non-powered attached parallel units. Closing the MOBs
may open or blow the non-active unit’s output fuses.

A UPS emergency power-off is initiated by the REPO pushbutton switch. In an emergency, you can use this
switch to control the UPS output. The REPO switch de-energizes the critical load and powers down the UPS
immediately, without asking for verification.
The UPS, including Bypass, remains off until restarted.
All power to the critical load is lost when the REPO switch is activated in the following step. You should use
this feature only when you want to de-energize the critical load.
L’alimentation de la charge critique est complètement coupée lorsque le circuit d’arrêt d’urgence à distance est
déclenché à l’étape suivante. N’utiliser cette fonction que pour mettre la charge critique hors tension.
NOTE The following instructions are for the Eaton-supplied REPO switch. If a customer-
supplied REPO switch is used, it may not activate in the same manner; refer to the
operating instructions provided with the switch.
